Mike Snitzer e00d89f257 devmapper: Add option for specifying the thin pool blocksize ...

Add dm.blocksize option that you can use with --storage-opt to set a
specific blocksize for the thin provisioning pool.

Also change the default dm-thin-pool blocksize from 64K to 512K.  This
strikes a balance between the desire to have smaller blocksize given
docker's use of snapshots versus the desire to have more performance
that comes with using a larger blocksize.  But if very small files will
be used on average the user is encouraged to override this default.
